FULLlNG-MILL.

SPECIFICATION forming part of Letters Patent No. 536,279, dated March 26, 1895.

Application filed March 3, 1894. Serial No. 502,189. (No model.) Patented in Germany May 2. 1893, No. 71,723; in Belgium May 2, 1893 Ila-104.500: in Austria-Hungary May 4,1893,No. 229,847: in France May 4, 1893 No. 229,847, and in England May 10,1893,N0.9,40'7.

To all whom, it may concern:

Be it known that I, ERNST GESSNER, machine-builder, of Aue, in the Kingdom of Saxony, Germany, have invented new and useful Improvements in Fulling-Mills, (for which I have obtained Letters Patent in the following countries, namely: Germany, dated May 2, 1893, No. 71,723; Austria-Hungary, dated May 4, 1893, No. 229,847; Belgium, dated May 2, 1893, No.104,500; France, dated May 4, 1893, No. 229,847, and England, dated May 10, 1893, No. 9,407,) of which the following is a full, clear, and exact description.

This invention relates to improvements .in'

fulling mills and has for its object to improve or accelerate the fulling action and so increase the output of the machine, without correspondingly increasing the space occupied, or the power consumed, by the machine. With this object the side hoards of the fulling trough are made movable and operated in such manner that they are caused to act as boaters in the lateral direction, their action being supplementary to, and alternating with, that of the ordinary stock, so that the fabric is worked or kneaded in two directions,'in consequence of which the fulling effect is greatly augmented and the goods are worked more uniformly than hitherto. The piece is also prevented from forming knots which is a great drawback to the existing fulling machine, as it necessitates the frequent removal of the goods from the trough for the purpose of stretching them.

The invention will be described with ref-- erence to the accompanying drawings, forming part of this specification, in which- Figure 1 shows a vertical longitudinal section and Fig.2 a plan ofa crank fulling mill provided with a single stock or beater, and Fig. 3 shows a similar view of a mill provided with two stocks or boaters acting reciprocally.

H is the stock, of the ordinarystepped form, hung by arms on a shaft X mounted in the frame G of the machine and oscillated within the trough S bya crank K'on shaft 0 to which it is coupled by a rod Z, the shaft 0 being provided with fast and loose pulleys s s and a fiy-wh'eel F at each end.

W W are the movable side boards of the said trough mounted to turn about shafts :13 90 these side boards W W being secured to lever arms Z Z the tail ends of which are coupled by toggle links Z Z provided with ball and socket joints L, L, L, L with the connecting rod Z which thus operates both the stock and the side boards W W so that the side boards are moved inward when the in the drawings, and outward when the stock is moved forward, as shown in dotted lines in Fig. 2. By this means the goods are kneaded, worked and turned alternately by the stock in the lateraldirection whereby the fulling effect is increased and rendered uniform. The axes X X about which the side boards swing, are inclined in a plane at right angles to the connecting rod Z when the crank K is at the dead point and the side boards are curved or hollowed out, as shown, so as togive free play to the stock in its to and fro motion.

I do not limit myself to a single stock, as a pair of stocks or beaters may be employed Working backward and forward.alternately. Such arrangement is shown in Fig. 3, in which a double-stock fulling mill in plan is represented, which is constructed substantially like the single machine.

G G is the frame work, S the trough, and C the double cranked shaft with fly wheels F F on each side and the fast and loose pulleys s s fixed to it.

H H are the two stocks which, by rods 2 z, are coupled to the cranks K K of the shaft 0, and. W W are the two movable sideboards of the machine, having their fulcrums in, and turning about shafts 00 ,02 The said side boards have lever arms y y at their upper ends, the tail ends of the lever arms being coupled by toggle links with ball and togrods are attached in the same manner with their opposite ends, by toggle links 2 .2 to the flywheels F F eccentrically, thus imparting motion in an oscillating manner to the side boards. This motion of the sideboards in lateral direction is of course always in correspondence to the alternate movement of the two stocks, so that the two side boards stock is drawn back, as shown infull lines,

in the ordinary way and by the side boards,

gle joints 2 z and secured to rods B B which IOO do not act simultaneously in the same direction but alternately to and fro, corresponding to the reciprocal movement of the two stocks.

The reciprocal movement of the two sideboards can be performed as well in another way, as shown for instance in dotted lines. In such case only one rod B is required to impart motion in the before described manner from the fiy wheel F to the side board W the latter being connected with the side board W by arms Z Z and connecting rod m from which the side board \V' is forced to go along with the oscillating movement of W In such case the lever arm y, and rod B with toggle links Z Z3 should be omitted.

I claim 1. In a fulling mill, the combination of a trough, a stock and mechanism for reciprocating the stock longitudinally of the trough, movable side boards disposed adjacent to the stock, and mechanism for moving the side boards laterally of the trough, the same consisting of link connections between the side boards and the mechanism for reciprocating the stock, substantially as described.

2. In a crank fulling mill, the combination of a trough, a stock, a cranlooperated connecting rod for moving the stock longitudinally of the trough, side boards provided with tail pieces and mounted on axes, and mechanism for oscillating the side boards laterally of the trough, the same consisting of coupling links coupling said tail pieces with the connecting rod which operates the stock, whereby the movement of the connecting rod will actuate both the stock and the side boards, substantially as described.

3. In a falling mill, the combination with the trough, the stock and a connecting rod for operating the same longitudinally of the trough,of movable side boards mounted within the trough on vertical axes and provided with tail pieces orlever arms, and toggle links forming connections between the tail pieces of the side boards and the connecting rod which operates the stock, whereby the connecting rod operates both the stock and the side boards, substantially as described.
